Question

if two opposite side angles of a pallelogram are (63-3x)digri and (4x-7)digri find all the angal of pallelogram

Answer 1

Answer:

1st opposite angle=(63-3x)

2nd opposite angle=(4x-7)

We all know, opposite angles of parallelogram are supplementary so,

63-3x+4x-7=180°

x=180°-56°

x=124°

1st angle=63-3×124

=-309°

2ng angle=4×124-7

=489°
